To me it looks like you're using an older Nuke color config. Check the one that says ..aces-v1.3_ocio-v2.1 in the dropdown of your project color settings.. then the Nuke viewer config should also say the same as mplay: ..SDR video (sRG - Display) instead of sRGB(ACES).

See if that improves it.

Submit as 'Bug' and set the category to 'documentation'.

For some distros this list isn't complete, you're still missing a dependency.

I would specifically check for that xcb-cursor lib that is mentioned in your error (I've had issues with it on another distro).
